Hey Francois
I was doing a deep dive into the latest PC app 2308.1. (Updated app and interface) Bike is a 2015 F700 GS.
Under Engine Controller/Service Functions/(off and online)BMSK Configurations there is a setting for wheel radius that lists 190/50-17, 180/55-17 and 190/55-17 none of which are remotely close to the OEM and current size of 140/80-17 this bike has.
Also under Vehicle Electronics/Service Functions/(offline)ZFE Configurations/Turn Indicators there is a setting for Rear Wheel Circumference that lists 1878, 1903, 1939 and 1981 mm again none of which are close to the 2018 actual of the 1/3 worn tire on it.
What would these setting do? I played with them and none seemed to have any effect on the consistently inaccurate speedo.
There is also a setting for Tank Capacity that has a list that goes from 3-37 litres with 10 steps in it (every size BMW makes?) 16 which is the tank size wasn't selected so I did, what does this effect?
You also show a selection for the Kombi 7 which this bike has (can-kombi-k7) but those choices aren't there.
Thanks in advance for struggling through this post
